What are some common pitfalls to avoid when creating a PHP image statistic diagram?

One common pitfall to avoid when creating a PHP image statistic diagram is not properly sanitizing user input, which can lead to security vulnerabilities such as SQL injection or cross-site scripting attacks. To prevent this, always validate and sanitize any user input before using it in your code. 

// Sanitize user input to prevent security vulnerabilities
$user_input = $_POST['user_input'];
$sanitized_input = filter_var($user_input, FILTER_SANITIZE_STRING);
